Abstract
The present disclosure relates to a steering control device and a steering assist system including same. Particularly, a steering control device according to the present disclosure comprises an input-side steering control device which includes: a first controller connected to an output-side steering control device via at least one first communication bus; and a second controller connected to the output-side steering control device via at least one second communication bus and connected to the first controller via at least one third communication bus.
Claims20
A steering control device for controlling an output-side actuator mechanically separated from an input-side actuator comprising:
- a first controller connected to an output-side steering control device through at least one first communication bus;
- and
- an input-side steering control device comprising a second controller connected to the output-side steering control device through at least one second communication bus and connected to the first controller through at least one third communication bus,
- wherein at least one of the first controller and the second controller is configured to,
- determine whether at least one communication bus connected to the output-side steering control device fails,
- output a control signal to the output-side steering control device through a communication bus in a normal state based on a determination result, and
- output, if the at least one first communication bus fails, the control signal to the output-side steering control device through a communication path according to the third communication bus and the second communication bus.
A steering control device for controlling an output-side actuator mechanically separated from an input-side actuator comprising:
- a first controller connected to an output-side steering control device and a second controller through a first communication bus;
- and
- an input-side steering control device comprising the second controller connected to the output-side steering control device and the first controller through a second communication bus,
- wherein at least one of the first controller and the second controller is configured to,
- determine whether any one of the first communication bus and the second communication bus fails, and
- output a control signal to the output-side steering control device through a communication bus in a normal state based on a determination result.
A steering assistance system comprising:
- an input-side steering control device for controlling an input-side actuator;
- an output-side steering control device for controlling an output-side actuator;
- and
- at least one public communication bus for connecting the input-side actuator, the output-side actuator, the input-side steering control device and the output-side steering control device,
- wherein the input-side steering control device comprises,
- a first controller connected to the output-side steering control device through the public communication bus and connected to a second controller through a first communication bus, and
- a second controller connected to the first controller through the first communication bus and connected to the output-side steering control device through the public communication bus.
